ACETYLENE-GAS-GENERATING APPARATUS.

Specification of Letters Patent.

Patented June 9, 1908.

Application filed October 27, 1904. Serial No. 230,278.

' generator, a rotatable feed plate located in said chamber to receivecarbid from said hopper, and a carbid discharge wiper surmounting saidrotatable plate and acting to direct the carbid therefrom when the plateis shifted in a forward direction.

Figure I is a view partly in elevation and partly in vertical section ofa gas generating apparatus with my improvement incorporated therein.Fig. II is an enlarged section taken on inclined line IIII, Fig. I. Fig.III is an enlarged vertical section taken through the carbid receivingchamber beneath the hopper that surmounts it. Fig. IV is an enlargedvertical section taken on line IVIV, Fig. II.

1 designates a portion of a gasometer tank and 2 is a portion of agasometer bell movably positioned in said tank.

3 is a guide rod supported by the gasometer tank and passing through abracket 4 carried by the bell 2.

5 designates the upper portion of a generating tank that is surmountedby a carbid receiving chamber 6 having a lateral extension that ispreferably disposed at an angle to a horipontal line taken through thegenerating tan 7 is a carbid hopper surmounting the chamber 6 andprovided at its lower end with a neck 8 that extends into said chamberand is ppen at one side, as seen most clearly in Fig.

10 designates a rotatable feed plate located in the carbid receivingchamber 6 beneath the neck of the hopper 7 and extending to the uprightportion 6 of said chamber to deliver carbid from said plate through saidupright portion into the generating tank 5. The feed plate is preferablydisposed at an angle to a horizontal line taken through the hopper necksurmounting it, as seen in Figs. I and III, and rotation is impartedthereto through the medium of a shaft 11 fixed to the plate andextending to the exterior of the chamber 6. This shaft is equipped witha pinion 12 that meshes with a pinion 13 carried by a suitably supportedshaft on which is a ratchet wheel 14.

15 is a lever arm having one of its ends located alongside of theratchet wheel 14 and bearing a pawl 16 that engages said ratchet wheeland acts to impart rotation to the shaft on which the ratchet wheel ismounted, from which similar motion is imparted to the shaft 11 and therotatable feed plate through the medium of the intermeshing pinions 12and 18. The free end of the lever 15 extends to the bracket 4 carried bythe gasometer bell to be depressed by said bracket for the purpose ofoperating the lever to rotate the feed plate when the supply'of gas inthe gasometer becomes depleted.

17 designates a wiper member that surmounts the rotatable feed plate 10and is loosely fitted to the hopper neck 8 to which it is held by studs9 projecting from said hopper neck and fitting loosely in slots 18 insaid member to permit of a limited degree of rise and fall motion ofsaid member. The wiper member 17 is formed with a forward and outwardlyextending arm, a, and a rear and forwardly extending arm, I), that arespaced apart and roject from the separated vertical edges of the hopperneck 8. A passageway is thereby provided for the carbid that descendsonto the feed plate through which the carbid passes to be dischargedfrom said plate into the vertical portion of the receiving chamber 6 andfall into the generating tank 5. The wiper member 17 is provided at itsbottom with diverging wings 19 (see Figs. II and IV). These wings restdirectly upon the feed plate and serve to revent the passage of carbidbetween said p ate and the bot tom of the wiper member.

In the practical use of my apparatus, the operation is as follows: WVhenthe bell of the gasometer associated with the generator equipped with myimprovement descends, due to the depletion of gas in the gasometer, therotatable feed plate 10 is rotated in a manner previously described.l/Vhen this rotation takes lace the carbid that has descended onto t efeed plate and is confined within the open hopper neck 8 and between thearms of the wiper member 17 is carried in a forward direction betweensaid wiper arms. This quantity of carbid is thereby forced against theforward wiper arm, a, and as said wiper arm prevents continued forwardcarriage of the carbid on the feed plate, the carbid is caused to traveltoward the edge portion of the feed plate overhanging the verticalportion of the carbid receiving chamber 6 and is precipitated over saidedge to fall into the generating tank 5. The rotation of the feed plateis continued through the actuation of the mechanism connected theretountil sufiicient carbid has been delivered into the generating tank to"create a volume of gas that will, u on entering the gasometer, elevatethe be 1 2 when the rotation of the feed plate will be discontinueduntil the supply of gas in the gasometer is again depleted subsequent towhich the same action takes place as before.

I claim as my invention:

1. In an acetylene gas generating apparatus, the combination with agenerating tank and a carbid holder provided at its lower end with aneck having an opening in its side, of a rotatable flat feed platelocated beneath said holder neck and upwardly inclined from the solidpart of the neck to the opening in the neck.

2. In an acetylene gas generating apparatus, the combination with agenerating tank and. a carbid holder provided at its lower end with aneck having an opening in its side, of a rotatable feed plate locatedbeneath said holder neck, and a wiper embracing the solid part of theholder neck and having arms extending beyond the opening in the neck;said feed plate being upwardly inclined from the solid part of the neckto the'opening in the.

fitted to said holder neck and having arms extending beyond the 0 eningin the holder neck; each of said arms eing provided at its bottom withdiverging wings resting upon the feed plate.

4. A feeding mechanism comprising a hopper, an inclined rotary flat diskreceiving the material from the hopper on its lower half, and a wipersurrounding the lower end of the hopper and having a pair of arms spacedapart to provide a passageway extending tothe highest 'portion of thedisk and a discharge opening at the highest portion of the disk.
